Paris: Andy Murray guaranteed his place at the World Tour Finals in London with a 6-3, 6-3 third round victory over Bulgarian Grigor Dimitrov at the Paris Masters on Thursday.

The 27-year-old Scot, who also stays on course for a fourth tournament victory in just six weeks, will now play either world number one Novak Djokovic or French showman Gael Monfils in the quarter-finals on Friday.

Murray joins Djokovic, Roger Federer, Stan Wawrinka and Marin Cilic in reaching the season-ending showpiece with David Ferrer, Tomas Berdych and Kei Nishikori in possession of the other three spots but not yet assured places.

Canada`s Milos Raonic is now the only player who can gatecrash the top eight but needs to win the Paris tournament to guarantee his place.

Murray aimed a jibe at his critics after the match who have said he has had a poor season by writing "Bad Year" on the courtside camera lens.

It is the seventh straight year he has qualified for the Finals although he didn`t play last year due to his back injury.

"I served really well and I don`t think I had any break points against me so if you do that and pick up a break or two that`s what I did," said Murray.

"It`s going to be tough against either Novak (Djokovic) or Gael (Monfils). I think Gael is one of my favourite players and he`s very popular with the fans here. If there`s one player I`d pay to watch it would be him.

"As for Novak, well he`s still fighting for the number one spot and very tough so they`re both difficult opponents."

Berdych is one win from sealing his place in London after easing into the last eight with a comfortable win over Spaniard Feliciano Lopez.

Following a first round defeat at the Valencia Open last week, the 29-year-old Czech evened his record against Lopez at six wins apiece with a 7-5, 6-3 victory.

Chasing an 11th ATP title, and third of the year, the Australian Open semi-finalist now plays South African 14th seed Kevin Anderson for a place in the semi-finals.

In other third round matches, world number two Federer chases a 14th straight victory, including tournament wins at Basel and Shanghai, takes on world number 176 Frenchman Lucas Pouille who came through qualifying.
